The use of indigenous microbes as a method of profile control in waterfloods is investigated. It is expected that as the microbial population is induced to increase the expanded biomass will selectively block the more permeable zones of the reservoir thereby forcing injection water to flow through the less permeable zones which will result in improved sweep efficiency
